 org.drools.util.ArrayUtils
| ArrayUtils | | public class ArrayUtils (Code) | | Taken from commons lang
Operations on arrays, primitive arrays (like int[]) and
primitive wrapper arrays (like Integer[]).
This class tries to handle null input gracefully.
An exception will not be thrown for a null
array input. However, an Object array that contains a null
element may throw an exception. Each method documents its behaviour.

| Method Summary | |
| public static boolean | contains(Object[] array, Object objectToFind)
| | public static Object[] | copyOf(Object[] original, int newLength, Class newType)
| | public static boolean | deepEquals(Object[] a1, Object[] a2)
| | public static boolean | equals(long[] a, long[] a2)
| | public static boolean | equals(int[] a, int[] a2)
| | public static boolean | equals(short[] a, short a2)
| | public static boolean | equals(char[] a, char[] a2)
| | public static boolean | equals(byte[] a, byte[] a2)
| | public static boolean | equals(boolean[] a, boolean[] a2)
| | public static boolean | equals(double[] a, double[] a2)
| | public static boolean | equals(float[] a, float[] a2)
| | public static boolean | equals(Object[] a, Object[] a2)
| | public static int | hashCode(Object[] array)
| | public static int | indexOf(Object[] array, Object objectToFind)
| | public static int | indexOf(Object[] array, Object objectToFind, int startIndex)
Finds the index of the given object in the array starting at the given index.
This method returns
ArrayUtils.INDEX_NOT_FOUND (-1) for a null input array.
A negative startIndex is treated as zero. |
| INDEX_NOT_FOUND | | final public static int INDEX_NOT_FOUND(Code) | | |
| contains | | public static boolean contains(Object[] array, Object objectToFind)(Code) | | Checks if the object is in the given array.
The method returns false if a null array is passed in.
Parameters:
array - the array to search through
Parameters:
objectToFind - the object to find true if the array contains the object |
| equals | | public static boolean equals(long[] a, long[] a2)(Code) | | |
| equals | | public static boolean equals(int[] a, int[] a2)(Code) | | |
| equals | | public static boolean equals(short[] a, short a2)(Code) | | |
| equals | | public static boolean equals(char[] a, char[] a2)(Code) | | |
| equals | | public static boolean equals(byte[] a, byte[] a2)(Code) | | |
| equals | | public static boolean equals(boolean[] a, boolean[] a2)(Code) | | |
| equals | | public static boolean equals(double[] a, double[] a2)(Code) | | |
| equals | | public static boolean equals(float[] a, float[] a2)(Code) | | |
| indexOf | | public static int indexOf(Object[] array, Object objectToFind)(Code) | | Finds the index of the given object in the array.
This method returns
ArrayUtils.INDEX_NOT_FOUND (-1) for a null input array.
Parameters:
array - the array to search through for the object, may be null
Parameters:
objectToFind - the object to find, may be null the index of the object within the array, ArrayUtils.INDEX_NOT_FOUND (-1) if not found or null array input |
| indexOf | | public static int indexOf(Object[] array, Object objectToFind, int startIndex)(Code) | | Finds the index of the given object in the array starting at the given index.
This method returns
ArrayUtils.INDEX_NOT_FOUND (-1) for a null input array.
A negative startIndex is treated as zero. A startIndex larger than the array
length will return
ArrayUtils.INDEX_NOT_FOUND (-1).
Parameters:
array - the array to search through for the object, may be null
Parameters:
objectToFind - the object to find, may be null
Parameters:
startIndex - the index to start searching at the index of the object within the array starting at the index,ArrayUtils.INDEX_NOT_FOUND (-1) if not found or null array input |
